One piece

Characters replaced by Luffy, Nami, Zoro and Sanji.
All characters are fast and agile.
The game has pretty smooth animations.
The voices also match their characters.
 Weapons removed from some enemies.
All bosses except JET have increased HP

This hack, it is based on the hack Dha Lau Hoo (https://www.romhacking.net/hacks/4592/).
Neutral Air Attack is now Air to Air. Works great for juggling an opponent in a corner or while playing in Co-op, but can miss when attacking a ground target.

Used sprites:

Known glitch:
In a two-player mode, if P1 chooses Zoro, the picture will be blinking during his combo finisher.
To avoid problems the second player should choose Zoro .
Also in a two-player mode, small graffic artifacts are possible for some enemies at the first and last levels.
